The working principle of the utility model is as follows: firstly, air in a system is exhausted through an exhaust valve arranged at the top of the chamber, so that the air is prevented from entering a condenser through the system to influence the normal heat exchange of the condenser; after the system is shut down every time, a blowdown valve at the bottom of the additional chamber is opened to exhaust deposited impurities in the additional chamber.

Under normal conditions, the industrial water pressure is greater than the circulating water pressure, the plugging material (usually sawdust) is filled into the additional chamber and then is brought into the condenser by the industrial water (the connecting pipe brings sawdust into the condenser through the circulating water in the circulating water inlet pipe, and the circulating water flows out through the circulating water return pipe), when the plugging material flows through a leakage point, the sawdust is absorbed to the leakage position of the heat exchange pipe under the negative pressure action of the condenser and is plugged, but the leakage point can be plugged, and the plugging material can be rotten or sucked into the steam side of the condenser along with the lapse of the running time, so that the leakage point reappears, and the plugging material can be added again to perform plugging by the plugging material, and the process is repeated until the pipe is stopped and plugged.

When the temperature of the circulating water is low in winter, the water supplement amount of the water cooling tower is small or the industrial water is stopped, the circulating water at the outlet of the condenser is boosted by the booster pump and then enters the adding chamber to replace the industrial water to run, but the power consumption is increased by using the booster pump, so that the industrial water is used as much as possible during normal running, and the circulating water is used as a standby water source of the industrial water
